CROSS REFERENCE TO RELATED APPLICATION

This application takes priority from and claims the benefit of U.S. Provisional Application Ser. No. 61/533,880 filed on Sep. 13, 2011, the contents of which are hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present system relates to ergonomic systems for individual usage and more particularly to portable and fixed ergonomic tray table systems and the like which may be utilized for multipurpose applications and stowed when not in use. The present system further relates to ergonomic tray table systems which are disposed for usage within vehicular applications.

2. Description of the Related Art

Concurrent systems and methods for tray table systems designed for support of articles such as food, laptops, books, magazines and other reading materials have been created for specific applications and purposes. A variety of concurrent portable tray tables have been fashioned for use in laptop applications as well as for passengers of vehicles.

In concurrent embodiments of portable laptop tray table systems, the tray tables are normally designed such that the user will be in awkward and non ergonomic position during usage. Many concurrent systems do not possess support mechanisms for typical table tray type apparatuses for supporting computers or reading materials and thus must be supported by the lap of the user. Thus, the useful features of these concurrent systems are often vitiated by the non-ergonomic effect on the body of the user.

In concurrent embodiments of laptop tray table systems designed for vehicle adaptation, once set in place in usage mode, the tables are normally distant from the user and provide no arm support for the user. Even in the cases wherein the tray table systems are adjustable to get closer to the user's body, these concurrent systems do not comprise ergonomic and body contour features.

Tray tables are typically stowed in the seatback of most passenger seats in a non-operative position, and are lowered into an operative position during flight. As a result of the stowage of the tray tables in the rear of the seatbacks, a passenger generally utilizes the tray table stowed in the seatback that is immediately forward of the passenger. Thus, tray tables are customarily connected to a set of arms which pivot downwardly from the seatback to an operative position. Other regularly utilized systems comprise a foldable-table assembly whereby both the seat and tray table rotate about a horizontal axis as a unit to enable the seat to recline or systems which rotate from a stowed position in the seatback to an extended position for passenger use.

SUMMARY OF THE INVENTION

The instant apparatus and system, as illustrated herein, is clearly not anticipated, rendered obvious, or even present in any of the prior art mechanisms, either alone or in any combination thereof. A versatile article support apparatus and portable computing device transport system, which assists the user in maintaining proper posture in utilizing a laptop. Thus the several embodiments of the instant apparatus are illustrated herein.

The present system relates to ergonomic systems for individual usage and more particularly to both portable and fixed ergonomic tray tables and the like which may be utilized for multipurpose applications and stowed when not in use.

In one embodiment, the instant device may comprise a portable laptop tray table system, designed to be compact enough to be carried on the person of a user. In an additional embodiment, the portable laptop tray table system may comprise provisions for carrying articles such as a laptop or other personal items, as the portable laptop tray table system may comprise a foldability feature, wherein upon folding the portable laptop tray table system for traveling, an enclosed area.

In an additional embodiment, the instant device may comprise incarnations including an armrest system designed to work with a normal desk assembly. In one embodiment, the armrest may be installed into an existing table or desk within the factory. In another embodiment, the ergonomic armrest system may be retro fit adapted to fixed tables in order to render the tables ergonomically viable. In the retro systems, the ergonomic armrest system may also be retractable, and may also be disposed to be invisible to the naked upon positioning in retraction more and may thus be contained in to an enclosed, hidden compartment. It is envisioned that the instant apparatus will encompass the identical construction to the portable system and thus provide ergonomic support for the user of a normal desk or table.

In an additional embodiment, the instant device may comprise a retractable laptop tray table system also comprising a stowage start here for moving vehicles, such as automobiles, trains, planes, and water vehicles. A tray table assembly is provided that includes a tray table and an arm connected to the tray table which extends from the rear portion of a seatback. The tray table is pivotable with respect to the support arm so that the same surface of the tray that faces upwardly during use that may become soiled also faces outwardly when the tray table is stowed in the seatback. A seat assembly is also provided that includes a passenger seat having a seatback defining a recess for permitting the tray table assembly to be stowed in the seatback. The seatback recess is shaped and positioned in such a way that a major surface of the tray table can only be positioned outwardly when stowed in the seatback recess, thus preventing the seat from facing the seat in the stowed position.

In a further embodiment, a wholly retractable system design for vehicle, school or office usage is exemplified. This system will comprise a storage area and an animated, actuation/retraction arm which will allow for ergonomic utilization of the table while providing “hideaway” storage of the ergonomic table and actuation/retraction arm.
